Abstract

A method and apparatus for realizing a stable focus jump operation even in a case where a waveform of an S-curve of a focus error signal fluctuates due to aberration due to fluctuation of a multilayer optical disk substrate thickness or the level of the S-curve fluctuates due to reflectance fluctuation are provided. A focus jump processing means (DSP 51) for performing a focus jump operation moving a laser spot among recording layers of a multilayer optical disk 10 having a plurality of recording layers corresponding to a record/reproduce operation for recording data on the multilayer optical disk 10 or reproducing data recorded on the multilayer optical disk 10 performs acceleration processing for moving the objective lens mounted on an optical pick-up from a certain recording layer of the multilayer optical disk to another recording layer, waiting processing, and deceleration processing for stopping the objective lens 34 and makes an impulse of the acceleration pulse added for the movement of the objective lens 34 in the acceleration processing larger than the deceleration pulse impulse stopping the objective lens 34. <IMAGE>
